DRAIN-FITTING.

Specification of Letters Patent. 7

Patented June 6, 1916.

Application filed August 6, 1915. Serial No. 44,021.

To all whom it may concern Be it known that I, CHARLES D. WESSELS, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Drain-Fittings, of which the following is aspecification.

This invention relates to the connection used between sinks, tubs, orother similar receptacles, and the waste-pipe or trap, and while it maybe applied to any stationary tub construction, it is particularlyadaptable to concrete tubs.

In the common plumbing practice as at present employed, for making thedrain connections from the tubs to the trap and waste-pipe, lead pipe isused and what is known in plumbers parlance as a wipe-joint is madebetween the drain fitting and the trap, or directly with the waste-pipewhen a trap is not interposed. While the wipejoint construction may besuitable and in common use, it has objectionable features, among whichare inconvenience for repairs and nondurability. In many instances,particularly in high grade laundry equipment and plumbing, iron pipe isspecified with more serviceable connections, therefore the objects ofthis invention are to provide a universal drain connection that isadaptable to either the wipe-joint, lead pipe plumbing or to iron pipeand more durable joints. Another object of the invention is to provide adrain fitting that can be easily and quickly connected with ordisconnected from the trap or waste-pipe, thereby facilitatinginstallation and repairs.

A valuable feature of the invention is its universal adaptability to thedifferent connections, thereby eliminating the necessity of providing aspecial fitting for each type of joint, therefore the present inventionprovides a more efiicient drain connection or fitting than hasheretofore been used.

To facilitate the understanding of the invention reference is had to theaccompanying drawings, similar characters of reference being employed todesignate similar in said drawings and in the specification. In thedrawings Figure 1 illustrates a portion of a double, concrete,stationary laundry tub embodying the invention, showing its connectionwith the two compartments of the tub and with a waste trap.

Fig. 2 is a vertical section on line 22 Fig. 3. Fig. 3 is an undersideview of the improved fitting. Fig. 4 is a transverse section on line l1Fig. 3. Fig. 5 is a view partially in central vertical section, showingone kind of joint. Fig. 6 is illustrative of a lead pipe wipe-joint.

Referring to the drawings 1 is a hollow casting adapted to be set intothe bottom 2 of the tub, and having branches 3 and 4: the chambersinwhioh open into the compartments 5 and 6 respectively. The casting 1is provided with a stem 7 having an opening therein which communicateswith the chambers in the branches 3 and 4. The exterior of the stem 7 isthe form of a truncated cone as shown at 8, and the interior of saidstem is threaded as at, 9. On the undersides of the branches 3 and 4 arebosses 10 provided with openings 11 and ledges 12' embedded in theconcrete as an aid to the anchorage of the casting 1 in the bottom '2,or the said opening 13 may be used for an overflow connection not shown.

If it is desired to use iron pipe, a simple and serviceable connectionis made by merely threading the pipe 15 into the opening in the stem 7as shown in Fig. 1. If lead pipe and a wipe-joint is specified, the samefitting 1 may be 'used, the mouth of the pipe 16 being flared in theusual way and wiped around the truncated cone portion 8 as shown in Fig.6. In the lead pipe, wipejoint construction a collar 17 circumscribesthe pipe 16 and is provided withflears18 through which the bolts 19project, the heads of the bolts resting on the ledges 12. Through themedium of the nuts 20 on the bolts 19 the collar 17 can be drawn upagainst the shoulder 21 formed by flaring the pipe 16, thus securing atight joint and supporting the pipe 16.

Fig. 5 illustrates a joint wherein the pipe 22 is provided with ashoulder 23 and is screwed into the stem 7, a collar 24 is drawn upagainst the shoulder by nuts 20 on the bolts 19, the same as in thewipe-joint construction. This forms an absolutely tight, 110

lock joint, as the thrust of the collar 24: on the shoulder 23 causesthe thread on the pipe to bind in the thread 9 of the stem 7.

From the foregoing it will be seen that the same drain fitting isapplicable to a variety of connections. I am aware that a drain fittinghaving a truncated cone stem has been used for lead pipe with awipejoint, but what is considered as an improve ment is the universaladaptability of the present invention, thereby increasing the utility ofthe article.

What I claim and desire to secure by Let ters Patent is- 1. A. drainfitting for laundry tubs and the like, said fitting comprising anintegral shell member having branches for connection with thecompartments of the recep tacle to be drained, and a stem for connection with a trap or waste-pipe, providing open communication throughsaid branches and stem, the interior of the stem being threaded toaccommodate a standard fitting and the exterior of said stem being atruncated cone.

A drain fitting for laundry tubs and the like, said fitting comprisingan integral shell casting having branches for connection with thecompartments of the receptacle to be drained, and a stem for connec- :3

a ioe thread to accommodate a standard 35 fitting and the exterior ofsaid stem being of truncated cone formation.

3. A drain fittingrfor laundry tubs and the like, said fittingcomprising an integral shell casting having branches for connec- 40 tionwith the compartments of the receptacle to be drained, and a stem forconnection with a trap or waste-pipe, providing open communicationthrough said branches and stem, bolt hangers on the underside of 4 saidbranches, the interior of the stem provided with a pipe thread toaccommodate a standard fitting and the exterior of said stem being oftruncated cone formation.
